Empty session files in tmp dir

[Anon]

Problem - the /tmp session files created in my tmp directory contain zero bytes (ie. totally empty). Any ideas why?
Here's my setup: Windows 2000, Apache web server, PHP402. I can see new session files being created each time a new session is registered, but they're not much use if they're empty! I've checked the file permissions on the tmp directory, and it's completely shared out. No error messages or logs are being generated that I'm aware of.

More background: The session is being used in a simple authentication routine. When a username and password are recognised on a MySQL table, the session is created and some of the user's details are assigned to the session variables. I expected to see these session variables appear in the temporary file that had been created. So initially I am successfully logged into my system, but the moment I try to navigate elsewhere in my 'members area' I am asked to log-in again because the session variables do not exist in the tmp file.

I'm sure the solution is something annoying and small!

Thanks.

Thanks for any help...

You have to register the session variables first after you call session_start()

Hi Manos,

It feels like I posted this issue such a long time ago that I can barely remember how I fixed it!

I my poor memory serves me correctly, then I think that indeed it was to do with making sure I was using session_start() correctly before registering the session variables. In other words, the problem almost certainly lies somewhere in the way you are organising your PHP code rather than your system setup.

Just make sure that session_start() and session_register() all take place right at the very start of your code, before anything else.

Luck.
